Thanks to all your help, the problem is solved.

Did the following change to the /boot/grub/grub.conf and /etc/fstab.

For grub.conf, I changed root=/dev/md1 to root=UUID=f91a794d-2bfd-44c5-abf1-c4ad8c4139bd
and added rd_MD_UUID=dce65261:eb5eb12a:9cf04c7a:ecbfd465

Code: Select all

---------- grub.conf --------------
From.

initrd /initramfs-2.6.32-754.24.3.el6.x86_64.img

-------- end grub.conf -----------

For /etc/fstab, changed to UUID.

Code: Select all

----------- /etc/fstab ----------------
From.
/dev/md1		/ 			ext4 	defaults,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0 1 1

To.
UUID=f91a794d-2bfd-44c5-abf1-c4ad8c4139bd               /                       ext4    defaults,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0 1 1

---------- end /etc/fstab ------------

Now the server can boot with just /dev/sda. Replaced /dev/sdb with a new drive and the Raid1 has synced up. All good.

Once again thank you to all who have replied and helped. I really do appreciated it.
